Research associate Shimon Kolkowitz and his colleagues in the Ye group and Rey theory group have developed a powerful new way to experimentally simulate the complex behavior of electrons in solids. In these experiments, the team uses its strontium lattice optical clock not to track time, but to take advantage of the ultracold atoms in the clock mimicking the quantum behavior of electrons in a lattice of metal atoms. Because the ultracold atoms in the clock can be controlled and measured so much more precisely than electrons in a solid, the electron simulator based on the clock can provide information that cannot be obtained directly from the solids or electrons. The team’s secret is coupling the motion and internal states of strontium atoms via their interactions with laser light. These innovative clock experiments will not only improve traditional timekeeping applications, but also could one day lead to brand-new materials or contribute to the design of reliable and robust quantum computers.

The advantages of the clock setup for reaching such long-term goals include not only precision control of the quantum states in each atom, but also novel measurement techniques and...
